Hi Memetix,
I really like the modern sheets look, and to be honest I hadn't looked much at the Gothic sheet. But now that I have, I do like that it shows the percentiles of the skills so you don't need to add all the numbers together time and again. And it looks very nice and easy too for quick reviews.
Other than that I find it useful to have descriptions for some talents or special abilities. Maybe you could let the player choose wether or not a description should show on the sheet. Like with the possibility to add a bonus to the skills, you could have a box with an option for a description, and if the user adds a text here it will show up under or next to the talent/special ability.
I would also like a small text showing what xp is needed for the next rank.
And that about it
Other than that it looks great!
