Plastic miniature quality and buying more?

I bought the collectors set as I am older and have a nostalgia for metal models and also(can, time permitting) paint to a high level and some plastic models have a certain angular look or have bad mold lines so had prepared myself for the game models to be lower quality. Having said that some of the plastic miniatures have really bad bits blobbed/blurred detail. My Gata model is really bad, I might have to Gstuff/Mputty some sharper edges on the cat mask to give the models some identity. I have read that Aristeia buyers models seem to vary though, I would be quite happy if there was a core character set available to buy reasonably priced, this would be good for mirror matches, alternate paint schemes too.

On a side note my young daughter has really taken to the look of the characters and wants to paint them. as a knowledgeable painter i know she should practice on my old models but that's not how life works, she wants to paint up Gata and Maximus, that's where she is getting the drive from.

Any thoughts Aristos?
