Actually that's the perfect first bike I'd say! I'm a little eccentric in that respect but a light, agile, controllable, superbly-handling and braking, reasonably powerful bike with linear predictable power ... is THE GOODS.
Do take care to set up the suspension just right for you. Dirt bikes have long travel so suspension dynamics have a great effect on handling and feel - small adjustments to suspension can make everything click. Don't be afraid to experiment.
