Jules, your paint job here is truly amazing! of course every artist feels the need to improve, that is what keeps us going. but if I were you I would leave the improvement up to the next project. The Guardian is great just as it is.
No need to say that I am looking very much forward to your next amazing project
I think its great to use stuff thrown at you, see what our brain comes up with, how to use them... thats why I like the challenge of beeing introduced to other ones ideas, customs or costumes, cover art... what ever... its another level of provocation ones abilities, very creative though sometimes frustrating... but we always fight to push the limit
