So I have a very big list of Marvel characters I've been working off of - this was the portion I was looking forward to the least because I simply am not familiar with about 90% of the Guardians of the Galaxy roster... But a list is a list and a goal is a goal and I plan to draw every freaking Marvel character on that dang list before the year is over! (side note - I haven't posted every character I've drawn, but you can see them all on my Instagram account if you feel like scrolling down for a few hours).
In any case, the Guardians of the Galaxy:
Drax, Bug, Major Victory, Rocket, Groot, Cosmo the Spacedog, Mantis, Adam Warlock, Gamora, Jack Flag, Moondragon, Martyr, Star-Lord, Thanos, Nebula, Ronan the Accuser... Ego the Living Planet is in there too, just not as prominent.
