Hi there
Your modelling and texturing is good, but I’m not getting a feel of motion from the picture, the characters - especially the dinosaur, need to be more dynamic.
The poses need to be selling the motion, especially in a cartoony illo like this where I would expect everything to be over-exaggerated. I see you’ve tried to convey that sense of movement thru motion blur, which is not helping - if you get the pose right you won’t need a blur effect, and if the pose is wrong a blur is not going to help.
One thing that might be tripping you up (no pun intended) is that it’s not immediately clear how the Dino’s legs work - I suspect he’s missing a joint. Either way, if he’s running, the figure needs to be more dynamic, and if he’s walking it shouldn’t have blur.
I think what you’ve done here is good - I love the dino head and the expression, but I think you’ve been too conservative in the posing - bigger, bolder, more dynamic gestures will lift this off the page.
