You could totally make a 1 point perspective drawing with this composition. If you’re putting the fish in the middle, I would push the perspective on the cat more. Gives it more dimension and space. Keep up the fun ideas

Your seals look great! I think they all look alive, you've done an awesome job finding the line of action in these. I don't have anything to say to correct anything, but you can look for certain things in the poses and try pushing them a bit further to increase the movement in your shapes. Here's a few notes and drawovers I made for these poses. You've already found these areas, but see if you can push it more. Look specifically for areas where there is a stretch and squish relationship happening, and even if it's minor see what happens when you emphasize it. You can also add complexity to your shapes by using combinations of straights and curves where there is weight being distributed -- the straights will indicate where the weight is being held, and the curves counterbalance the structure with gesture. You may find that you push it too far that it doesn't work, but then you know where the outer boundaries are!

if you never experienced something like that, it means one might haven't gone far enough. It's not healthy of course but at same time this is a sign that person is motivated and connected enough that the time they devote matters to them and are looking forward to make great things in life. I am experiencing this, have from day 1, but now when I think about it, those crash outs were important to figure out somethings, I think these things help to face and accept your failures or things you lack in, and all you have to do from there is work on your weaknesses.

this is really good

You're not off by much at all! Really it's just the width that is slightly too short. Not bad by any means. It takes a while, but the next time you do one of these you'll find easier, and so on and so on :)
