This is great artwork from a beloved Final Fantasy game X. The staff was from Lady Yuna and he quest/pilgramage. I loved that story and I love FF series. I think your sunsetting was good but needs a starburst of light coming off the staff to give more effects of importance. You have a slight glow of that going on already but I'd prefer a sunburst going into that. I love the tropical coloring that matches the game coloring and island setting. The trees and shadows are all very well done. The staff itself is the star here and is a great piece to look at and reflect on that great game.

More shine and sunburst from the sun to staff but overall a great fan art
