He bears a resemblance to Daenerys Targaryen's dragons when they were babies —you won't know what I'm talking about if you're not a fan of Game of Thrones, but that was a compliment
Like toe_head recommended above, scales are needed for a dragon to look dragonish, even for baby dragons —and I think they should look fine on baby cat-dragons too I would say don't worry much about the size of the scales, although if it's going to be a baby dragon you may consider scales that won't stand out too much, but that can be easily appreciated at first sight. I want to emphasize that he looks like a baby dragon as per the size of his wings (let's remember that adult dragons tend to have huge wings according to popular draconic myths, but I'm probably stating the too obvious —just making conversation here). Other than that, I think he looks quite like a dragon ? (nicely accomplished concrete wall, btw)
PS: You may pay a look at this tutorial, especially the finished piece at the top of the page. You will see some discreet although perceptible scales above the belly area.
