Your space background is excellently well done, considering the use of colored pencils. I had a rather difficult time doing this with my piece, which was primarily done with colored pencils, and opted to using a free digital image of a nebula as a result. What brand of pencils did you use?
As far as the composition of the piece went, well done! I like how you took liberty to add a bit of detail to the Rogue Star. Additionally, the captain (girl with pink hair, sorry forogt her name) is very well drawnand colored, portraying the personality of the character.
I also like your lighting effects. They are mastefully executing and believable.
