Hello Vitalino,
Your painting is good, but the shade of blue is uncorrect. May be you have used some grey to give ligjhts on the blue? The sky blue has to be more...bright, not fading in grey, or so seems from the photos
Before add the sabretache and his belts, cut a bit the belts of the sabre, they are too long
Bye bye and good forwarding
