Sorry for the long wait! Please, don't hit me!!!

But now I've finally gotten it done ... so what do you think?
mccow28: Adjusted the hair to follow the movement of her head, but that made one of her nipples show a little so maybe I should put a nudity warning on this now?

I also adjusted her left breast. I put it slightly lower, as she's not sitting perfectly straight.
Keops: Thanks for the C&C! I made the black into a lighter (but still very dark) blue-grey. I'm glad you like my colour choices!
D39: The tail has been redone!
Godslayer: I've removed the black outline there, but I really liked ptoing's help with the water so that's what has been implemented.
rabidbaboy: As stated above, the tail has been redone. I studied some fish tails before I cam up with what it looks like now.
ptoing: Thank you soo much for the edit. It was a great help with this piece. Especially the reeds and the water was improved by the help you gave me.

I did not do it completely your way though. For example the outlines; I kept them... but made them lighter in tone on some places, and I did AA a bit better. The merging of the gold and skin colour was a great idea, so I did that as well and that left me with the possibility of adding another colour, for which I chose a very light blue so that I could make clouds and AA them nicely. I intended to have them in the piece from the start but I ran out of colours. I added highlights to suggested places, but much more on the tree than in your example, and I think that made the leaves fit more into the style of the rock and the mermaids scales. Brought the picture together so to say. I did add a face to the mermaid. But in my own style. It looked good with your edit, but it was very ptoing-ish...and compared to my style it looked like an angry make-up artist had attacked her

Other things I did was to slim the wrist, and change the palette a tiny bit, though I did not go really as saturated as your edit is.
Actually I do not always do very clean lineart before I start adding colour. With this piece I did a ver rough lineart, but refined it on the tree and her face before adding colour. But lineart is just a part of my style I think. I do it with all my art, and I think I've just subconciously done it with my pixel art as well. I'll try out your method next time I pixel something. Thanks for the AA help as well, I've tried it out all over the piece.
Helm: I really liked the green tinge you had given to the rocks so I've used that idea, although I did not really like some parts of the highlighting on the rocks and how you made the shades purplish like... But thanks for the help and suggestions!
Tisha: Aww, thank you!
Toby: Thanks for the compliments, I've done quite a great deal of edits to this based on ptoing's!
pkmays: I kept to sort of a middle line here... made the outlines lighter, but did not remove them completely. Thanks!
Soup: Thanks! And done!
snake: Your edit was some great help on the shoulder part. I've taken parts of it into consideration like the square-ish shoulder and the arm. I think the ribcage edit made it a bit too portruding. But I have edited the tummy/ribcage area to show her pose like you suggested, and I also gave her some hipbones. The edit on the apples was very nice, but I don't think it really fits the style of the rest of the picture. Approve of the new fins?
Dusty: Follwed your suggestions about the black outlines. The fins are edited. The styles might go better together now? Although in nature things do have very differing textures. But there's more details to the leaves of the tree and the tree trunk to make it all fit together now.
Adarias: I really liked your edit of the face, still not really my style though, but I used your edit for base reference. And yeah, the light is pretty much fucked up... unless maybe, the tree is leaning out, from us.
Sohasu: It is not as much highlighting as it is her hair being toned from blonde to green... actually.
Fool: Hey, thanks!
cave: Nice edit on the tummy there, I did something along the lines of your edit.
Derek: Added lots of clouds to the background and changed the horizon a little. Better? Anyways, thanks!
Everyone was a great help to my improvement of this piece. I just hope you all think it
has been improved!
