- Yes, the rotation is not that important it could be basically any angle, all the collision will depend on collider shape and it can roughly match the rotation of the object. I started simple, made it in the 3/4 perspective without having too much trouble. The perspective problem and redrawing is fine i am not in a hurry, the project is just my hobby to fill my spare time. I needed this to just test my current skills, test the time i need to draw things like this and consider quality (thanks to all of you for help with this). Now i will try to draw some smaller objects (barrels, crates) to get the colors and perspective right.

- I also missed the scale, because i have 16x16 pixel tiles, and i expect that the characters will be 16x32 max. This can change but it will have impact on my whole system, all the tile sizes will change, pathgraph for AI will change etc. so now i keep it small like in old jRPG. Also with the sizes i choosed, i don't draw 64x64 character sprites when i can't draw a well yet:D The well is now 80x80 and that is too much. It should be max 64x64, maybe 80x64 but it depends on the other elements like houses, doors, crates, barrels  etc.

- As i see there is plenty of things to consider, i don't know where to start first but i don't think i can make good palette without experience, so i just focus on drawing the shapes as best as I can and discuss colors here with more experienced people. I will definitely draw some smaller objects and then try to rework the well into that scale and perspective.

I made an update. I combined suggestions from all of you:
- palette change suggested by Rhubarbist
- roof shape suggested by alanxoc3
- well poles change by IncorrigibleBoozehound and also added bucket with rope



Now this is by no means finished. I realized, that i have problems when drawing small objects. I saw it when i tried to draw small parts of the roof in first version of the image, now i saw it when i tried to draw the bucket. I think it is still easier and better to draw smaller things when learning, but since every pixel matters and errors stands out more i am struggling.

For the bucket - only the front parts looks like wooden bucket :-). There is also bad contrast with the well, its because i wanted to share colors from the well (for the metal parts) which didn't work. But still i can't get the right contrast especially the left part of the bucket. I could place the bucket near the poles but i wanted it to be on the well.

Another thing which i am not really happy is the roof and the poles that goes now to the ground instead of well. I think the roof does not have enough detail but maybe its just my impression, but the poles definitely coudl have some details. Again i discoverd that my problem here is with rouned objects. I had hard time drawing the poles so they look like cylinders, i cannot imagine getting detail on them so they still look like cylinders.:-)

p.s.: Sorry for long post, i will be trying more and maybe post another update we will see how it develops. I am also be no means an artist and i will never be, i'm a programmer so my interest is whole different area. I'm just trying to learn pixel art for 2 things:

1) I really like it and enojyed it in old games and i will be really happy to have some knowledge of this art.
2) I need some graphic in my mini - game i am working on in free time and i have no one to draw it. 3D modeling, texturing and animating these things is out of question, no way i could learn this in reasonable time so i choosed pixel art and i think i can get some graphics by myself.
3) It is a great relax from programming when i am thinking about pixels and no code:-))

Thank you very much, this might work and i can get more detail to bigger planks than to small if i need to. I will try to make it this way, thanks for help.
