Hey Jiang, I've seen your arts recently and they're quite enjoyable. You seem to be comfortable doing unusual and dynamic poses like you did that Sky Uppercut Breloom or that Muk, which is great, although it could be better if you could incorporate light source and shadings (with lines or color) into your next artworks; that way, it would make them look less "flat" and 2D'ish and make them seem more polished. Practicing sharper & well-defined outlines could also help.
Also, I love that Godmaldo btw -- the silhouette, dismal sky, the thunder, the outline around the buildings; fuckin glorious. I'll look forward to your next artworks!
