Not bad, others ones have started worst. All your gallery is nice, but it could be better. For example, fake designs looks cool but also empty. Add details, like stripes, horns... Or details that do that you can know the type of the fake by only see at it, but no by the colour (with this I mean that in a fake you can know it's type by see, in water type, the animal one has choosen and the details, like shells, fins...). Lights are ok, but you add a lot of black outs. Black outs only should be on the shadow part, not on the light part. You've got the basic idea of how to do tiles, but to do them better you have to fill all the empty spaces. For example the wall of the blue roof's house (add windows), the wall under the roof (windows or details), etc. Be sure you will improve with the practice, keep going! Greetings!
