Awesome, awesome image! You have a subfolder with your name on it in my inspiration directory.
Its strange to hear you stay stuff like “I’m trying to do better and more colorful illustrations I have that problem”. Sometimes its easy to forget everybody is learning. Even the artists you admire. 
I like the colors and composition of your last work a lot. Those are all things i’m just learning/reading about myself. The way you create repetition by angling the arms of the “little one” the same as the shins of the “father one”. The way you border the lower frame of the picture. The value contrast with the antlers all pointing back to the head. Even the straight antlers on the little one play a role in guiding the eyes. The longer I look the more I see! 
I find it an awesome piece and very inspirational.
Kind xmas greetings to you too,
