Hello Steve,
A start is always difficult but the completion of the model shows the artistry.
As Billy(turnip) said above and many others, when you see a box art or another master's work this is not
at all a discouraging thing but the opposite, to see learn and try to make these according to your potentials,
the main thing is to enjoy the hobby and be satisfy with your achievement.
Personally i admire the work of many master painters here because i can see that their talent and creativity
are endless.
Your start is a good start and waiting for your next progress post!!
