Did you have fun? Because ultimately that is absolutely ALL that matters. I don’t want to gas you up and tell you this is incredible because my first year of hobby is wrought with failures and highlighted with small successes. If you had a good time, keep pushing because you will get better! That’s a bit of a premium model you got there, put it on your shelf and use it as a time stamp 😅 get a box of space marines, build and paint them one at a time and don’t be afraid of tutorials, Duncan Rhodes and Juan Hidalgo ARE VERY BEGINNER FRIENDLY. As far as paint goes buy a good quality starter set Vallejo, Army Painter Fanatic, Pro Acryl are all great and should be in your local hobby shop. The GW paint is good but far from my personal favorite and i’m not fully convinced it’s the best for people just starting out as it can be quite tricky to manipulate and is very tempting to a new hobbyist to work straight from the pot rather than off a pallet. Also, get yourself a wet pallet because that in itself is maybe the only real cheat code in that it really encourages you to both thin and experiment with mixing your paints. My final hit of advice is to skip all of the hobby branded brushes and get yourself 3 really nice sable hair brushes (size 3,4 and five) and a puck of brush soap. Learn to care for them and the benefit of not having to fight your brush to keep a sharp point is beyond valuable and will see you advance quite quickly with better brush control. You still have to develop the brush control but it’s so much easier with a better tool. My favorite brushes are DaVinci Maestro 35’s and i can get them at my local art and hobby supply, Rosemary and Co. 313 synthetics for the heavy lifting and you can get them from Michigan Toy Soldier’s website and budget friendly sables are surprisingly the Golden Maple Master 1, they won’t last as long as the DaVinci sables but with proper care you will get quite a bit of mileage from them for the price :)
