I’ll give some advice.
For one the palette is fugly. Look up hue-shifting, it will help make things look better.
The shading on the sword makes it look like a brick on a stick, because the highlight is to the far left of the blade, and the shadow is at the far right. Instead try putting the shadow down the middle, with a brighter strip on the right and keep the highlight on the left but extending to the tip of the blade.
The apple isnt bad, but I would bring the highlight more towards the right and make it bigger with possibly one speck of highlight near it (has a nice effect).
Also, outlines can improve these but dont use black. Pick slightly darker colors than the shadows. The sprite in particular would benefit from an outline because it looks washed out. Changing the palette will help here too.
The sprites dimensions are off in several places. The shoulders are too wide. The elbows shouldnt be visible from the front. And the feet are spread outwards too much. Do an experiment and stand up normally. You should notice that your feet are more parallel with your line of sight if youre looking straight ahead.
Hope that helps.
It does, mostly.
My advice for everyfuckingbody around here is that just because you are working with a 2D engine does not mean you automatically must aspire to be good at pixelart. Because you will not and it is not worth it aspiring for.
Just because there are some good pixelartists here, just because the general trend of “indie games” is using pixelart, does not mean that you have to do it. It just turn you into yet another retro wannabe. If you feel that you ducking have to do graphics (it would also be worth considering if it actually is something you feel comfortable not only doing but also showing to people after you do it) how about not being a mindless drone and try something new?
This forum is filled with subpar or downright horrible “pixelart” to the point where adressing single threads in showoff is a waste of time, because they all lack the same thing - and that would be talent. So, dear reader… ducking stop. Pixelart is not for everyone, and if it’s not for you, that’s fine. Maybe there’s something different you can do with your free time.
I’m not improving pixel art most for Eclipse, just so I can make cool stuff with it.
