Caffeine

Is this the right molecule drawing of caffeine?

If not, what's wrong about it?

Its ok.

https://en.wikipedia.org/wiki/Caffeine
i've seen a few different drawings and some of'em say H3C
instead of the CH3 on the left lower corner. Does that make any difference? Oh, and in some of'em, small part is on right and the larger part is on left (i'm pretty bad at chemistry as you can tell), what about that?

It doesnt matter if you write CH3 or H3C you can turn the molecule so its also ok to have the bigger part left or right or on top or bottom.

The nit picky response:
On the left hand side, it looks like the N-CH3 bond is going to the H3 rather than the C, which is a typo.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Chemists (sometimes programs) draw molecules in a such inelegant mode.

Yes? What is it that I've misinterpreted? Whether you write the group as CH3 or H3C is not relevant, the bond should connect to the carbon atom. As written, the structure is easily understood, but can be drawn better, which was the original question of the thread.
