The pieces on him need more blending, they look a bit pasted on but the humour is there solidly affecting the viewer.

cute doggy.

You can extract that lightening very nicely with "Calculations" set to "Grey + Gray and Multiply". I don't have a mic but I made a video for you to show you how to do this lightning VERY VERY quickly and very decently. Mind you, this is a good extraction, but there is more to it if you want to get it better. You will have to research this more if you want to get into absolute perfection, but what I showed you in the video is very fast and mostly good enough. I advice you to research Calculations (as well as Channel Masking). It is an extremely powerful tool!!

Also there are "hair/grass" brushes in Photoshop. I think they are #133 and #134 or there abouts. You can use them to mask in the cat's antennae rather than just putting a black dot over them. Hope this all helps.

The comments given to you above are a goldmine of information, not only for you but to those of us struggling. I love your idea, it is truly creative...just needs polishing up.

YOU DREW THIS !?! Did you use a WACOM tablet. I would not have minded to see a bit more detail of background as the clipping (block ups) detracts and could be used as a great "backup singers" tool. There appears to be some incongruity around the tail. You have the shadow down pat, but parts look pasted on. The colour palette used gives a cool feel.

Your escape from misery adds to my misery recognizing how limited I am in creativity when it comes to chop and paste and manipulate as you have done. I come to this side of the site and get stimulated, inspired and encouraged and your work has done that for me....so thank you....

Members like Skyangel and BWR frighten the beegeebees outta me, their work is stellar and I just "fave" their pieces, study them, sometimes write to them to get more in depth responses, which they always give. Slowly, some day ! Thank you for your encouragement.

This reminds me of the BORG from Star Trek (the episode with HUGH). I find the nose a tad of a distraction as it is not in focus. Woof!
