So... first time I've made a sprite...
Not really sure what more to do with it to be honest - general outline is that it's a destroyer class (350 pixels) - wanted to go from a mash up between Tri-T and Heg look and feel, almost as if it's been made from two designs.
Hi,
First thing I noticed immediately is that the contrast isn't there yet. Depending on the program you're using, you could possibly adjust the levels to make the dark colors darker and lights lighter. However, I'd save that for last, as if you're like me, when you're painting things or fiddling around manually with the graphics you don't darken and lighten things as far as you should.
I like the shape of the ship, it's unique and not one of those "Aww yea it's a giant doom ship" things that people always seem to be making. You can add depth to your ship by shadowing around the outer edges a bit, the softer the shadow, the smoother and more rounded the surface, the sharper the shadow, the sharper the surface.
I like the coloring of the ship, I wouldn't change any of that.
I hope this critique helps, I look forward to seeing what you come up with.
