Fullmetal Alchemist Volume 27 fanart

AAAAA I'm just really proud of this fanart, so I wanted to show it ^^ I made the sketch on a paper and then I scanned it and used my computer to make the lineart and the painting
Fullmetal Alchemist means a lot to me (I was like, what, 9 or 10 years old when I first watched Brotherhood) and since I finished collecting all the volumes, why not make a fanart, yk?

Also, if you guys have any suggestions about improvement and stuff please tell me, I'm quite a noob at digital art lol. I'm planning to make a Saint Seiya or an Astolfo fanart next
