I just love your sprites.
Dude, you know how when you offer negative criticism it's good to include some positive lines too -
in this case I think it's a good idea to try to find some kind of feedback or relevant commentary to go with your praise - that way we'll keep everyone constantly cheering each other on, pushing each other to improve and learn O:
as a mod, I usually just delete one-liners that don't offer critique, but at the same time all conversation might turn out useful, like Olonthor's mention of the DoDonpachi influence, that might get an interested pixel newbie to search out the original - I mean that's useful
we're treading a fine line, us modsers : D
sooo.
crits.
upper area of blue glow has severe amounts of banding - since the pixel lines are stacked on each other they create crazy psychological visual phenomena making me see vertical lines in the rifts between stacks - not good, creating additional aliasing. You should AA and break up the pixel clusters.
I'm not too hot on the yellow and the green in combination, they're not contrasting in the hottest way. Are you really happy with the colors? then don't mind me. If you aren't, please do experiment!
The green parts of the main core are striking me as somewhat jaggy. Simplify those shapes for a visually pleasing result.
Also are there more assets to this project? Lasers and explosions? THEN POST THEM * U *
