Presentation: Is using cartoon slides un-professional or fun? I am close to graduating and am going to an assessment center for a very large tech company. One thing we need to do is hold a presentation about one of their products.

I want to stand out a bit from the crowd and show that I spent a lot of time on this presentation. So I had the idea of drawing my own characters and using them in slides to help explain my reasoning etc. (A lot like in the youtube-videos you see nowadays where stuff gets drawn while a person talks). 

I find this type of presentation fun to listen to, but is it unprofessional? It is my first time at a global giant like this and I'm sure they are fine with more than others since it's in tech, but is this too much? Should I use the normal "boring" slides with one idea/slide etc. ?
In general, the person talking to your slides should be you, not a cartoon character. 

Now, I've seen things like this work for people who are very good presenters and stage performers as well. For example, one of my grad school compatriots was also a serious performing storyteller, and he understood the performance aspect well enough to do all sorts of fun, risky, and showy things in his talks.

If something like this isn't already you, however, then I would advise not trying it for the first time in a potentially high stakes presentation like this. Conservative may be relatively boring, but it's also safer, and it won't be boring, if your material is good.
