It seems that your sofa didn't really have a sense of depth to it. the main bit it seems to be not thick at all. I made a quick edit here:



I also added a shadow to make it match the table. Perhaps adding a shadow to other objects.

Thanks a lot BlackFang. Your point about the shape of the head helped me out tremendously.

I ended up redoing a lot of it, I didn't like how wide I made the hair. It made it look very "wild." So I slimmed it down quite a bit. I also removed or changed some colors that I thought were redundant or unnecessary. The difference is mostly unnoticeable, but it's there.

One problem I have with this walking animation is that it seems that the character's feet are point outwards as they are moving, it gives it a almost coical feel to it. Tell me if you disagree, but I just think that the feet should point more inwards. If you try walking normally, you will naturally see that your feet generally stay straight, they don't bend outwards.

I have actually decided that I am going to use a larger tileset but something seems wrong with either the colouring or the formation of my main grass tile.

Here is the tile:



Anyone see anything that is drastically wrong?

...You should really increase the contrast though.

Is this enough:
 

Today I started work on a grassy platformer tileset. here it is:


Here is a 'very' quick mock up of what a level would look like with this tileset.



I am new to pixel art so this is probably bad. Any suggestions for anything would really be appreciated.

I  think that it is probably a bit repetetive with the texture and I really don't like the grass, can someone modify it for me.
