Interesting ideas, man, but the flames would burn those feathers, hahaha!
Those fusions do not make much sense... Why don't you try something more plausible, something that you can adapt to the real world, like a Charizard with feathers?
Does this really matter? I mean seriously these actually look really good, who cares that they wouldn't work in real life?
Overall I think these are really good, I like that though they are predominantly still the birds they have a good integration of the lizards as well as the colouration is superb, well done.
