Welcome 
I like the scenes you paint, with a bit of storytelling. The blood on the hands is very well made.
For your last piece, i think that the branch under the bird is too saturated and goes from a dark color to clear white. My eye wants to look at it, but it's blury.
Lastly, colors (at least for trees) don't reach white unless it is under a really hard light
( Tree with light and shadows for reference)
Can't wait to see your other artworks
