How long do your works typically take you?

How do you get faster? Or am I just getting 1-shot by social media and the "rkgk" and "just a lil 15 min doodle" type posts and only freaks are fast?

When it comes to speed I don't know what the hell I'm doing wrong.
It's like at some point I just become blind to how much time is passing.

I had a warmup today that I hated, so I forced myself to put together something that I liked the look of. That took like 40 minutes to get the base sketch down. Then from there it's just refining it, adding in more detail, etc.
My -plan- was 3 characters and a background and now 7 hours since I started I'm only kind of refining character #2.
I'm having fun with the process but I feel like I'm so goddamn slow. The fun and good feelings I have just get crushed from that.

I keep hearing that "mileage is what matters" which I get it, I have for a long time
>want to get better at art
>just fucking draw and don't be a midwit
But far as mileage goes it feels like I'm just puttering along at 10mph while everyone else is on the highway.
