well well well what do we have here.
looks quiet good for a starter. my compliments

there are just 1 thing that bothers me.
the two side wings in the back.
they seem a bit lower than the rest of the ship.
did you intend this?
if so it would look better if they were darker so that it matches there position more.
another thing, it doesnt really bother me and its not wrong or anything ,but for a ship this big its quiet... simple.
i am missing out some more details,
although that just my opinion it may be that the faction which uses this ship has the same style of smooth ships.
i think some more details like vents, lights, piping, maybe some mechanical stuff would finish it off.
just one more thing.
Keep drawing! I like it if people draw sprites from scratch
