@ashinmakes Thanks a lot for all your observations April! You don't have to have a degree on art to be able to see how to improve an image, I myself dropped out of an art degree (A decision that still haunts me). Anyway, I certainly feel you on the composition points and consider it very important! Now, the reason behind this simple camera angles I have chosen is based of the nature of the project that is an imaginary cartoon, so the backgrounds are depicted as some kind of "base", or in a establishing shot fashion so the audience knows where all the action happens (the playground and the classroom) and how they look, and if you give the storyboards a look you'll see that basically this is what is needed on the most part. Regardless, you are right, I'll give the scene a more dynamic look the next time
Now, on the colors I tried to make the BG as flat as possible so the characters with their green, and blue clothes would pop up, it could be revisited tho, painting their fur with cool colors as well.
And finally on the images being too bright, I have to admit I didn't do it so the image wouldn't look so interesting with shadows everywhere, but then again, it could be interesting to try it.
Thank you for your comment, I look forward to hear more feedback in the future because for years everyone has told me "oh that looks so nice" and that's that.
