So... You want to draw pictures, or more specifically, a comic.
Well, this software is built around this particular use case. It can also do illistrations, but it's not built around that use case quite as much as it is comics.
You have the vitual 'paper' of the page to be drawn. You don't draw directly on this, like in MS paint. You have panels. For an illistration, a panel can be the entire page. When you're making a comic, you'll have more then one, and you can easily resize and move them around a bit after drawing them. It also allows you to distort the whole panel if you want. There's lots of options there. Inside these panels, you have your standard layers, like in everything that's not MS paint.
It will take mouse input, so you don't need to buy a $100 tablet (or $250 tablet-equipped laptop) but if you have one, that also works. It has drawing guides, like French Curves for us Drafting people, that let you draw smoothly with either method.
It's cheap, Buy it once and you're done
Has some tools very useful for it's inteded application.
has figures you can pose to get a sense of scale, this is REALLY nice if you're like me and utterly stink at drawing characters.
Has nice export functions, and some limited vector graphics capibility (it's a raster program, so no exporting)
Doesn't chew up too much memory, while you're running.
A fair decent selection of brushes and the like.
Has guides, even mouse drawn stuff can look good.
Perspective grid <3 so much less involved for basic outlining of that sort of scene.
The pressure sensitivity for tablets isn't there (at least on the t730 it's not) it also doens't change the cursor to tell you it's getting it's cues from the pen, it's nice for me to have that visual feedback so I know when I can let my palm rest.
Editing spines is TEDIOUS. Avoid using them when you can.
The toolbars on the sides don't stay inside the window, so it can cover the start bar or end up half offscreen when I rotate the tablet..
It lacks a classical 'ruler' with mm/pixels/inch measurement, it IS nice to have that now and again. Not so much a con as a feature I miss dearly.
Could use more figures. A hand is one example I'd love to see added. I tied to add one myself (You can do that!) but it failed miserably.
It could use some tutorials, but I know those are slowly coming.
Lacks a plugin API that I know about (if it has one, I can think of at least one handy plugin to add, I'd make it myself if need be)
All in all, it's not a bad program. I've doodled with it quite a bit, using both the tablet on the laptop, and the desktop, and have yet to have gotten really annoyed at anything. I've gotten faster with it as time goes on. Would (and have) reccommeded it to other artists I know
