Welcome to the Guild Konnel . Well have you tried some of the tutorials here yet? Allot of people come here doubting their artistic skills but find that after attempting some of the tutorials, they are capable of much more than they had dared to hope. Since you have GIMP, check out some of the many GIMP tutorials on offer here and post up a WIP once you've begun. That way others can offer helpful feedback. Best wishes to you.
