Look really good for your first model mate :3 keep the good work up!
got base coats down with a wash looks good
tbh better than what I ever did when i started painting about 1 year ago.
the photos are abit hard to see try taking photos with good light source, and a white background

but from What i can see only thing I can really say you cuold improve on "from this photo"
is the sigial on the arm it looks like it sbeen drowned to much in wash and is almost black try re highlighting that part leaving the blackwwash in the deep recesses try doing that for the weapon and that aswell looking forward to some updates

I've only been painting for 1 year and I think i'm doing on check my gallary out. Will monitor this thread for a reply from you :3
your stuffs looking great
