I enjoy your art style and hope to see more as this was pretty detailed, you bring a stylish and nice style here your art is pleasent and hope to see more soon. This was a lovely piece I love the use of color in this one, and think you could have made the baloons brighter and adding a few more baloons in the distant just an idea though, the boy is genuenly happy and thats a positive piece, one thing I noticed was two elements maybe its just me looking into things too much but theres baloons that represent modern times, and theres his clothing that may date him from another time? but anyways nice job here. do make more and present us with this lovely art style that brings many lots of joy including yourself, because at the end of the day if you enjoy it thats all that matters anyways nice work.

If it wasn't for that one line at the side of the one eyebrow I think he'd really be looking really genuinely happy... that little thing seems to turn his smile into a bit of a forced one. Otherwise love the art! All those balloons too. Simple but solid style.
