THREE years in the making!!!
Pencils and inks by "Martin" over on Deviantart. The file also has the name "Skyboy" in it but whoever has the moniker 'Skyboy' there now isn't the same guy, so I have no idea beyond 'Martin' as to who did this.
I've had this picture sitting half done on my HDD for 3 years and I usually do a little bit between other pictures as I decide what to do next or when I'm waiting on a commission or Zenescope file to come in. So, overall it means the colouring is a little inconsistent...
But tonight I was watching a live spacewalk from the ISS on my other screen (as you do...) so started colouring this one again (motivated!!!) and this time finished it off.
