Nice idea, with perhaps some space for improvement. To give the heart a tiny bit more attention, you can put it a bit higher (it could juuuust fit with the direction of her eyes). The moon can be flipped so it's more clear that the brightest part gets light from the window. And maybe left and right of the image it could be a tiny bit cropped, but that's of course a personal decision. Masking the different photos look ok. Good luck!

I think enlarging the window might lock it more together.. I don't know, it's what I would do,(the hummingbird makes my heart melt.. and you set it on fire LOL.. good luck )

(sorry, some more blabla)
DS may have a point about the window. It can be enlarged or what you also can do is lower the moon & girl. This way there's more space between the moon and window (which are kinda the same size and fighting for attention) and on top of the image the hummingbird gets more attention because it would be a little bit more above the girl tha on the same level (so it's easier to see what the girl is reaching for). Up to you, of course. Good luck!

ack.. listen to WAZ, I have no right to entertain my ideas in this venture.. good luck author.. great job all round.. it's already a great Idea

Thanks, guys, I'll see what I can do... actually, something was really bothering me on this work, but I didn't know what it was. I think the points you showed me were the problem. Maybe.

Nice idea - probably having darker shadow on the right side of the moon can synchronize the lighting source direction? anyway, great artwork

I have the same feeling, if the moon has no light of its own and she should be enlightened by the window, the "dark side" should be facing to the right.

Thanks for the tips, friends! Changes were made...
