The same reason for both.

Istock seem to like to see strong drawing in their application files (although that sort of artistic image doesn't seem to sell terribly well once you start submitting!) All the examples on this thread are likely to be rejected by istock for applications. (and most  are likely to get rejected for the collection once application is passed). They just aren't sophisticated enough. You need to think about consistency of line, style (so not mixing up gradients  and flat shading in an unsubtle way) lighting (so that if you are shading the implied light source comes from a consistent direction, perspective (can be distorted for effect but must be handled consistently within any one drawing) and colour.

Once you are in it's easier to get the more commercial stock vectors accepted - although they seem to have got tougher on the not for stock rejections in the last year -and I haven't submitted much as I don't do commercial I just draw for pleasure and it doesn't sell. (although the few I do sell make lots of $$per sale as an exclusive)

These weren't application files, just regular uploads.

After what you said I think I'll stay away from iStock until I can get to a "professional" vector level... It sounds like the ones they like are way above my level. I just submitted to a couple of agencies as jpg, not eps, so we'll see what happens.

I'm shocked!!! My silhouette of the boy fishing....of course with just a light yellow background, I did away with the sun and stars.....got excepted at SS and depositphotos....I am truly shocked. Still wanting on BigStock. I only uploaded the jpg's not EPS. 

Now it's time to celebrate with the creation of the next masterpiece!!!!!! I know I don't need for it to go to my head but heh at least I can enjoy the moment!. 

I'm slowly learning them...I working on a goofy looking man...or woman...riding a bike. We'll see how that goes. Oh and it is from scratch..
