Well you have the approval of this old Nova fan! Great rendition - love the pose and the background! I've added it as "subject to your approval" addition for my Nova Prime group. More than welcome to visit. I actually contribute regularly to the main Nova fan site, Nova Prime Page - we have a fan gallery there...love for you to submit this for inclusion. At the Group..I along with a host of fellow Nova/DA artists do the Nova619 webcomic for NPP and Cosmic Book News.
Check it out. We're presently looking for 1 page contributors for our Group's first artist jam for the December episode to round off the first year online. Welcome to take part if you have time.
