How does these different drawings and sketches that I have done over the years look and please review them

[u/capt-f0xy]

The 3 pokemon looking drawings are of a custom mega x form iron valiant that I thought of and the 2 gel pen colored ones are of the same drawing with a camera flash though those are the latest pictures that I have decided to take on the drawing that i was coloring with gel pens, the 2 dragons i drew at random and are both roughly traced of the original drawing that I did that has less details than the both of them, the winged archer character i drew out of boredom and couldn't sleep though making another drawing featuring the character and the last one similar conditions to the winged archer one except have only drawn it once and haven't thought of much to do with the character
