Hurray! I'm glad to see some more art, Warrior. It looks good.
The animation looks excellent.
- so THAT'S how it happened. I'd always wondered. You've captured Tintin perfectly - it looks very good.
The quane baby looks awesome too - I like it's furry texture. It's - is halter the right word - looks cool, too.
I'm not sure what type of photoshop you have but I'll try and help with the brushes problem. I don't know how long you've been using photoshop so I'll try to cover some of the basics as well, sorry if you already know them. You might also have a different version of photoshop, but I'm hoping this same method works in most versions.
Usually I would go into the brush tool (b is the shortcut). Up the top, immediately under the File, Edit, Image, Layer etc. menu bar you should see another menu bar with brush options.
You will a picture of a brush with a down-pointing triangle at the start of the menu. Go to the next one, which is a word
Brush: with a little preview of your current selected brush shape and another flipped triangle.
If you press that triangle you should get a drop-down list of different brush shapes, with a slider bar up the top which says
Master Diameter. You will use that slider to increase/decrease the size of your paint brush shape.
Those first shapes will give you a crisp, sharp line that I find really good for linework. If you go a little further down you'll see brush shapes that look blurred - good for soft edges. Even further down, you should find some odd ones that look like grass/fur, maple leaves etc. Those grass/fur brushes are really excellent for a simple furry texture.
I hope that helped somewhat. To get back on topic: Your pictures look awesome and I hope you continue to explore the digital media.
