Well, it is really nice to have you in the VGMaps community, and I'm really glad you share the forum's love here! I'm sure you'll enjoy some time hanging out here! Welcome!
And, yes, the process can be oftentimes long, depending on maps' sizes, but, with building endurance and confidence, you'll get the hang of it in no time.
Once you have all the game's maps finished, which is always nice, you can submit the maps to the site so it can be seen in the Atlas very soon.
