Fantasy Trio Guards Ornate Wooden Door

A fantasy game cover art illustration, full shot, depicting three characters in front of a massive, ornate wooden door set in a stone archway. From left to right: a large, moss-covered rock golem with glowing yellow eyes, a grey alien in a black hooded robe with glowing purple and blue magical energy emanating from its hands, and a bipedal rat rogue wearing a tattered trench coat, holding a dagger and a smoking bottle. The art style is detailed digital painting, reminiscent of classic fantasy RPG art. The lighting is soft and even, highlighting the characters and the ancient door. The mood is adventurous and mysterious. Earthy tones of brown and grey for the stone and wood, with vibrant magical blues and purples, and touches of green moss. Text overlay at the top reads "ALL STAR UNIVERSE" and "A game I day dream about from time to time".
