set up looks great. i myself have a 3 month old one. and use a 10 gallon tank. i have a heat pad under her hide, so at night she can go into it if she needs to warm up. i have a similar water bown like yours, only difference is i have a heat light, which it helps my temps but kills humidity. so i purchased a mini humidifer and rigged in into her cage, and have both set on a timer. works like a charm! best of luck, great looking snake!
