Looks very nice'n cute! ^v^
(though, lemme give you some constructive criticism - the bench looks kinda flat, the whole scene perspective not allows to show the depth of this object, as the result the bench looks like just 3 flat lines, you could use some extra shadows, texturing or color gradient to imitate the perspective)
Everything else in your artwork looks just fine, hovewer! Love it!
P.S. oh yeah, one more thing - it'd be easier for someone to find your cool artworks if you added tags to your picture :P

Thank you Apec for your advice, it's really nice from you <3 It's my partner, who did this background and I didn't touched much of it, to keep it hers.
In my view I see it like "cartoon" or "anime" scene, which is kinda basic, but keeps this nice colour balance.~
Ours' other YCHs have more realistic backgrounds than this, so it may look kinda new ^^~

I will keep this in mind! I wasn't sure about tags (I add them just on sales) :D

I love this <3

Thanks~
