I drew three of these this week since work at my job was slow. For those of you wondering, I use Crayola markers as my medium http://www.rich-parno.com/aa_artwork.html
Nice style you have going there, very vibrant and catches the eye. That X-Wing variant one is quite dynamic and quite like the colour scheme on it too. I recognise the designs of the last two and it is nice to see art based off that period and wasn't expecting to see them.
These are very striking and so clean at the same time. The colourizations are very strong within the compositions. I personally think you executed the styling perfectly, you should be so proud.
