I use Elements too! The best way I've found is when you are drawing the line art (make sue you have a sketch layer first), zoom in are far as you can. This Tutorial is really helpful too (It says it a coloring tut, but she shows you how she does her lines too).
I use to use Photoshop elements as well and had the same issue. Not too long ago I switched to CS 4 and no longer have that issue. I would recommend if you cant afford to buy a new program that you try using higher dpi as well as a larger canvas. Once you finish your line art, you can scale it down.
What program are you using? PaintTool SAI has a really good stabiliser that gives much smoother lines, but if you're looking for a free alternative, I suggest FireAlpaca, it's free and the stabiliser works as well as SAI's. Another option to consider is using no lineart. When I just started digital art my lineart was super sloppy (you can't imagine...) so I did lots of lineless drawings, it took the stress off having to make a meticulous lineart, and it still looks pretty good (: My lineart's gotten much better (it actually doesn't hurt to look at it anymore) but I still prefer lineless because it's so hard to make super clean lineart OTL
Lineart unfortunately is just one of those things, some artists just scan in their lineart, I don't even use lineart much anymore, on occasion if the style suits. Its just practise, steady lines and some form and flow are from learning how to be confident, how to draw the strokes in a quick motion, which lessens the shakey/wobbly feel.
Cools! I think it takes practice, I'm not expert but I know I'm in the same boat and have pondered the same question. What I do is I draw a sketch in photoshop (or sketch it in pencil and paper) then turn it to 50% opacity, and then redraw again in a thinner brush size. I think my lines have become less wobbly with practice. Someone gave me a tip to make sure the brush is hard too.
Hi, You didn't link to a specific example or tell us what program you use, so I'll give you the general pointers.
1)sketch first then make your finished line art on a new layer. 2)Try to use longer, confident strokes instead of petting (multiple small strokes to make up a line). 3)Experiment with drawing with your whole arm for long lines (instead of resting your arm on the tablet and using your writs to draw (both methods can be useful I think) 4) line control improves with practice so practice a lot. 5) some programs offer line smoothing or stabilization, but it's probably best to improve your own control so you can work in a variety of programs.
