I agree with Jim and Tomo. I wouldn't worry about putting your own stamp on things just yet.
Coming up with your own presentation for a trick is good, but far from essential. I am sure there are some people who've been doing magic longer than you've been alive who do the patter for tricks exactly as written! In some cases, there really is no need to change it.
Changing the method for a trick is more risky, for the reasons Jim explained. Lots of "new" versions of tricks are actually inferior, because they miss out something that was essential, and this doesn't just apply to inexperienced performers. I remember a review of a book of card tricks that said most of the routines were actually inferior variations of tricks by other people, and the author of that book was a well-respected card magician! Of course, the reviewer might have been wrong, but he made quite a compeeling case (as he was able to cite the changes and why they made the tricks worse).
Even changing a presentation can cause problems. Sometimes a move or bit of patter is there for a specific reason, such as misdirection or even to make sure the spectator does the right thing.
Master some tricks and get a better grounding in performing magic in general, then you can start tinkering!
