Oh he's so cute! I have a betta too, his name is Saturn and he's a delta tail. Petco is dangerous because I fall in love with all the bettas and want to bring them all home, lol.
I see you have a heater, You're gonna wanna make sure that's fully underwater. They tend to be wonky if they aren't fully submerged.
I really like the decor, it looks nice
I like using the terracotta pots too. A tip, though: Everything needs to be smooth so it won't catch his tail. If there are any rough/sharp spots on anything, it should be removed (or you can use a dremel tool to file it down). And if you ever go down the fake plants route, they need to be silk. Petco has decent ones for not too much.
And I'd suggest more hiding spots, I think they recommend about 50% cover. That's what my betta has (1 decoration and several silk plants) and he's very happy. If you see bubbles on the surface of the water, in a big group near the edges, that means he's happy! Bettas make bubble nests when they are happy. My betta likes to form his on the underside of his leaf hammock, lol.
Other than that, I think everything looks really good! The 10 gallon was a wise choice. With time he will use every last bit of it.
I'm sure you and your betta will have a wonderful time together!
