Hey there!
So, notes on this one, her right orbit is a bit large and square (note how it kind of rounds down more, hugging the eye, the glabella is a bit wide, chin small and neck webs a bit too close to her chin. As for nose, are you using a little pyramid construction for it?
I feel you on energy, it can be hard sometimes and “life”gets in the way. When things aren’t going as planned I need to take a step back, if possible block agenda and take some days off of everything!
It’s essential to double check the basics: healthy food (low carbs/good carbs, plenty of veggies, fruits and hyrdation), exercise, good sleep, keeping good relations, cleaning clutter, avoiding energy sinks (games books media or anything that you’re doing just because you started or paid for it - but is not really giving you joy or is not a priority atm). Being mindful and practicing gratefulness - just letting yourself really enjoy and being grateful for the things you enjoy, the little simple things in life, like a delicious moka pot coffee in the morning or nature in an afternoon walk) I feel these basics can make or break you (if neglected) and have a HUGE impact. Of course also keeping in check any health conditions with appropriate professionals as well since any illness or lesion can hamper your efforts
As for time working on one thing, I think your ambient has a lot to do with it and your personality so I think everyone will be different in this respect. I love working on art in cafeterias, in my office at the clinic or in my gaming/art room at home. I usually listen to music while doing art and start myself up with some gesture or doodle/exercises. If i need inspiration i look at some art online or open an art book (James Gurney!)
Cheers!
