Not bad at all for a second attempt. Your construction and painting look very good.
Here are a few pointers;
On the tail decal (transfer) I think I can see some silvering, this is when air gets trapped underneath the transfer. One way of dealing with this is to give the model a coat of gloss varnish which will help prevent the air from getting trapped, then a coat of matt varnish to give the finish you want and to seal in the transfer. Doesn't always work as I sometimes still get silvering on my models, but it does help a lot.
I see you have also painted the frames for the canopy. To improve the look you can mask the frames with cut up bits of masking tape to get straight edges. You can even buy masking sets that saves having to do any cutting, but these can be quiet expensive when first starting out. Also before painting the top colour onto the frame paint the cockpit colour, then it will look like the inside frames have also been painted.
Hope that helps, only meant to be constructive criticism. Keep on doing what is good for you and what you enjoy. As John the Pom always says 'We do this for fun'.
