For starters, here how the drawing look like!

and here is how it looked like, as a sketch!

After "cleaning up", I had to draw the gun, but not any gun. The "Smith and Wesson" Model 60!

This one!

I want to draw it realistically too, like the guns in the anime "Gunsmith Cats".

But... I suck at drawing realistically.

Here's how I drew it before looking at reference XD

Then, I looked at reference, and drew the shapes. But... The gun looked too small. I mean, the gun is already small IRL, but still!

Then, I wanted to go on details. But it got worser (and smaller too!) as I added details...

I took WAAAAY too long trying to draw the perfect realistic S&W Model 60...

Finally, I just drew erased the whole gun, and drew them as I used to!
