4% won't be strong...that's a session my friend.
Bottle carbonation is a range thing. It's generally 2-3 weeks while using dextrose. 3 weeks is max and is what I usually shoot for.
You can get away sometimes with 2 weeks if it has been aging longer in the fermenter.
Since you racked it after 2 weeks (which is a good safe "mimimal" time to assure fermentation is complete for common brews), I'd expect it to taste better, but not HUGELY better, after 3 weeks of bottle conditioning.
FWIW, a good upgrade for you would be to get rid of the vertical fermometer stickers and get horizontal ones. Horizontal ones are MUCH better for many reasons that I won't go into.
Your vertical strip was placed incorrectly and I can see lots of air gaps due to the exterior ribbing of the carboy. You won't get an accurate reading unless that sticker is 100% firmly sealed to the glass! It says 66F on the glass, but who knows what the actual reading is....after 3-4 days of fermenting it will slowly work its way down to room temp. Nothing to worry about, just knowledge for you.
You should always plan/expect for a +10F increase during fermentation. So if it's 66F ambient, expect that it "may" reach 76F during peak fermentation, which is much too warm for an ale.
Congrats on making beer! You'll soon learn that:
1) Yay, I can make beer now, and 1G of beer is the same effort as 5G of beer, so why not just do 5G?
2) Wow, beer takes nearly 1.5 months from start to finish. Maybe I should make beer every couple weeks so I can always have something new ready to taste?
btw, Nice Buick.
